Tooth wear is the loss of hard tissue of multiple aetiology and may be due to functional or parafunctional factors. Depending on this, a restorative treatment should be chosen based on the severity of the wear, as it can result in loss of vertical dimension of occlusion (VOD), tooth sensitivity, and decreased quality of life. In these cases, the choice of restoration strategy must follow evidence-based treatment protocols, which include direct and indirect restoration techniques, as well as minimally invasive treatments based on composite resins that emerge as an alternative to conventional restorations of ceramics. This clinical case describes the treatment of a patient with severe dental wear through oral rehabilitation with composite resins through direct and indirect techniques, with the aim of preserving the tooth structure as much as possible and having greater aesthetic-functional...

Hypoplasia is a defect in the development of dental enamel that presents with various alterations in translucency, morphology, and color. The affected teeth can cause sensitivity in patients, are more prone to developing cavities, and present aesthetic problems. To address these issues, minimally invasive treatment alternatives are available, such as restorations with infiltrative resins in pediatric patients and the use of porcelain veneers in adult patients. Recognizing the causes of dental hypoplasia is essential to mitigate the progression of the enamel development defect and to determine appropriate restorative treatments. This study aimed to evaluate restorative treatments using infiltrative resins and porcelain veneers in patients with dental hypoplasia. An investigative/descriptive method was used to identify bibliographic sources on dental hypoplasia and restorative treatments. ...

The restoration of a root canal treated tooth with change of color represents a challenge in the current dentistry, since in some cases it is not enough to perform only one procedure that is the appropriate one in our opinion, but it is possible to consider choosing a set of them to obtain satisfactory results. It is not sufficient to know the forms of the dental pieces if these are not homogenized with the other ones in all their aspects; consequently, the color gains vital importance to perform a good restoration procedure. By applying procedures such as internal and external whitening, as well as composite resins, suitable results can be obtained giving back the patient the aesthetics and function lost. In this article, some basic criteria are detailed to be taken into account in the resolution of a case of dyschromia combining whitening and composite resins procedures; the results ob...
